Drag-able tab control?

In software like Photoshop there are quite a few panels with tabs that can be dragged to change the workspace. I have been thinking about making these kind of panels myself, based on container controls.

I downloaded the demo. Looks awesome.What I was first hoping for was a way to have a group of panels with tabs. (kind of how the standard tab-panel works, but with your appearance.)And that individual tabs can be dragged into other groups of panels.Photoshop has that to re-arrange several property panels to adjust the user's workspace.

But maybe I am just making things over complicated. That's why I was looking for existing solutions. And yours looks nice and is theme-able.

@Bob Keeney Hm...dragging a tab into a different tab panel is doable but challenging.

Before I was trying to create a transparent DragItem with an image blank image (color of the panel's background) and the size of the panel.As RawData I just passed the ID of the panel. So, when dragged into another panelgroup, it will remove the content from one group and adds it to the new group.

For a "panel receiver" I thought about using a PagePanel. When dragging the DragItem over the "receiver", it checks if the UTI matches. I set the UTI of the dragitem to be something that can hold a dynamic groupType name. So, I can somehow make some PanelGroups accept certain panels, and refuse others, that don't match the groupType.That way I can keep property panels together with other property panels... and panels I use for viewers or editors together with other viewers and editors.

What I try to make is a Subtitle Editor. I had one that works with SRT and Netflix in the past. But want to make a better one. One that has more the look and feel of software most video editors use. I use Premiere. So, I want to get the look and feel of the Adobe software to make it easier to use for people already familiar with that software.Of course it will not be a 100% match. But close enough.

A timeline will be one type of PanelGroup. Caption, Track and Project property panels will be another. And a third group would be the viewer, with a captioned-video display (a canvas showing the current frame, with caption, timecode, safe-area overlays, etc)

Mac, Windows, and Linux all handle TabPanel a little differently. Mac tab panels are just pills at the top. I know Windows will do multiple rows. I don't actually understand your request, as neither really has "grouping." Would you be able to mock something up in regard to grouping?

You could use BKS_TabControl with a PagePanel for the most simple implementation.
